Description

The older format of the trash checkpoint for 1.x is yyMMddHHmm the new format is yyMMddHHmmss(-\d+)? so if you upgrade from an old cluster to a new one, all of the entires in .trash will never be deleted because they currently are always ignored on deletion.

We should support deleting the older format as well.
